MULTIPLE-WIRE CONNECTOR.

To all whom it may concern:

Be it known that I, VERLIN PAUL GRIN- DLE, a citizen of the UnitedStates, residing at Lincoln, in the county of Lancaster and State ofNebraska, have invented certain new and useful Improvements in Multiple-Wire Connectors, of which the following is a specification.

This invention relates to a multiple wire connector, and moreparticularly to that class of connectors which would accommodate armoredwire, especially that class known as B..X.

The object of this invention is to construct a connector in such amanner that more than one B. X. armored wire can be laid to aswitch-box, plate, cut-out cabinets, etc., through one connector,instead of having to use a separate connector for each of said armoredwires, thereby effecting great saving in time and material in 'theinstallation of such apparatus.

In the accompanying drawings Figure 1 is a top plan view of theconnector showing the armored wire leading thereto; v

Fig. 2 is a transverse vertical section on line 22 of Fi 1; J

Fig. 3 is a iOllZOlltfil section taken on line 33 of Fig. 2; and

Figs. 4 and 5 are views showing modified forms of the connector. 4

A, indicates a multiple connector which may be made of any suitablematerial, pref erably some material which is somewhat pliable, forinstance malleable iron, or the like. The hollow body portion 1 hasleading thereto, from one end of the casing, parallel inlets 2 and 3,which are adapted to receive sets of electrical wires 4. and 5 coveredwith the so-called B. X. armor. These inlets are of such a size as toreceive the armor. The opposing wall portions of the inlets 2 and 3 arebrought together somewhat as shown in Fig. 2 to more completely surroundthe armor, and are drawn together by an adjusting screw 6 to moresecurely hold the armor within the connector.

The opposite end 7 of the connector ter- Specification of LettersPatent.

minates in a single circular opening, which provides an outlet for thesets of wires carried' by the two armored leads. The end 7 is externallyscrew-threaded, and provided at its base with a shoulder 8.. Thisshoulder limits the insertion of the end 7 into the apparatus to whichit is to be applied, the connector being held therein by suitablelock-nut 9 received upon the screwthreaded end 7 of, the connector.

In Figs. {l and 5, I have shown two modified forms, which show apossible construction when making the connector of such metal as wouldnot be so pliable as themalleable iron.

In these instances, the parallel inlets 2 and 3 and 3 are provided withdividing walls 10,, while the adjusting screws 6 are arranged in theouter walls of the casing, as clearly shown.

It will thus be seen that I have devised a connector which isparticularly adapted for use in connection wlth B. X. armored wires orsimilar armored wires, which is comparatively inexpensive, andyet'particularly adapted for the special use for which it is designed. I

I claim:

1. A connector comprisin a hollow body portion, formed with paral e1inlets at one end, the opposite wall portions of said inlet being curvedinwardly toward each other, means arranged between said inlets fordrawing said wall portions together, and a single outlet at the otherend of the connector.

2. A connector comprising a hollow body portion, formed with parallelinlets at one end, the opposite wall portions. of said inlet beingcurved inwardly toward each other, means arranged between said inletsfor drawing said wall portions together, and a single outlet at theother end of the connector, said outlet being externally screwthreaded,shouldered, and provided with a lock-nut whereby said connector can beheld securely in place.

3. A one-piece connector comprising a hollow body portion formed withparallel inlets at one end, the opposing walls of with a locknut,whereby the connector may which are provided with means arranged bebesecurely held in place.
